COOKING-STOVE.

SPECIFICATION forming part of Letters Patent No. 407,149, dated July 16,1889.

Application filed March 2, 1889. Serial No. 301,804. (No model.)

To (0Z5 whom it may concern.-

Be it known that I, VAsAN M. BARRETT, a citizen of the United States,and a resident of Atlanta, in the county of Fulton and State of Georgia,have invented certain new and useful Improvements in Cooking-Stoves; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to that class of stoves commonly known ascooking-stoves, the obj ect of the invention being to so improve suchclass of stoves as to render them more economical, especially where afire is not required all the time, as is the case ordinarily in usingthis class of stoves.

As ordinarily constructed, the oven of a stove of this class is muchhotter at its ends than at its middle, for the reason that the chamberunder the oven is divided into three parts or fines, heat in the twooutside ones generally passing forward, while the center one carries theheat toward the back of the stove, and this heat is of less intensity inthe center. flue than in the two outer ones, which does not heat thebottom of the oven uniformly. Then, also, in stoves as ordinarilyconstructed a damper is necessary, which opens and closes a flue leadingdirectly to the chimney to increase the draft by avoiding the frictionof the smoke, &c., passing through this divided line under the oven, andthis damper is necessitated by the fact that the draft is much lessenedby the length of and turns in the flues for the passage of smoke, &c.,whereas if these turns in the tlues were done away with and the flueshortened under the oven and the construction improved so as to allowthe passage of smoke, &c., around the oven at the first starting of thefire, much fuel and the time consumed in starting a fire would be saved,as almost immediate use could be made of the heat evolved in thestarting of the fire; also, a fire less than would cover the gratesurface cannot be built in these stoves without allowing a mixture ofcold air with the heated air passing through the fines, which isobviously disadvantageous when a small fire only is required, any excessbeing so much waste of fuel. I obviate this difficulty by a novelconstruction, whereby I am enabled to divide the grate-surface and tosupply draft to either or both parts thereof at will.

This invention consists of details hereinafter described, furnishing astove that can be sold cheaply and that will have points of merit as toeconomy, as hereinbefore briefly stated, which is of advantage,especially to those consumers requiring a cheap stove.

In the accompanying drawings, Figure 1 is a perspective of this improvedstove, showing the construction thereof in all particulars except asregards the flue passing around the oven. Fig. 2 shows the invention inlongitudinal section central to Fig. 1, showing in particular the fluepassing around the oven, thence to the pipe, and further showing thedivision of the ash-box into two parts.

In the figures like reference-marks indicate corresponding parts in theseveral views.

A is the flue.

B are deflectors.

O is a draft-damper, there being one of these said draft-dampers at eachend of the ash chamber F, dividing the same into two compartments, onedraft-damper C opening into each chamber.

The flue A passes from the fire-chamber E backwardly over the oven,thence downwardly, passing under the oven and the ash-chamber, andupwardly outside of the ash and fire chambers into the pipe, soot beingprevented from forming in the corners formed by the top of the stove andthe sideplates by the deflectors B, which also direct the smoke, &c., tothe pipe. This flue, passing, as it does, directly around the oven, thefire in the chamber coming in direct contact with the front plate of theoven or bricks thereon, and the heat spreading the entire width of theflue, heats the oven uniformly throughout, and the flue being direct,with no return-fines therein, lessens the friction of the smoke, &c., toa minimum, thereby obviating the necessity of a damper and allowin g theheat to be utilized in the oven from the very starting of the fire,instead of waiting, as heretofore, until the fire has gained sufficientheadway to allow' of the damper being closed, the draft beinginsufficient until the fire is sufficiently large to heat the air in thechimney to draw the smoke, &c., through the tortuous flue around theoven, as stoves are ordinarily constructed. This construction of flue isone through which the smoke can pass freely, and hence reduces thedeposit of soot and ashes to a minimum, there being no obstruction toimpede the free egress thereof, or to which the soot would adhere andbuild upon. 1

As hereinbefore mentioned, the ash-chamber is divided into twocompartments, furnishing, in eifect, two draft-fines to carry air to thegrate and virtually dividing the grate into two fire-surfaces, and, asthe draft can be partition D may be made, as shown in the drawingsthatis, by forming it integrally with the bottom plate of the ash-chamber,it being bent therein in the form of an inverted V, or by placing asimple partition therein consisting of a plate of metal of the desiredsize and thickness. Forming the partition from the bottom plate of theash-chamber is the preferable form of construction, inasmuch as itpresents the under surface of the bentup portion to the cooling actionof the air in the flue, which is practically cold at this distance fromthe fire, being cold enough to prevent the heating of the partition tothe point where it would burn out. The flue is also restricted slightlyat this point by the deflectors B, and this notch enlarges the area ofthe opening to nearly the size of the largest part of the flue, and thatWithout a detraction from the operation effectively of the saiddeflectors.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is

In a cooking-stove, the fire-chamber E, the ash-chamber F, subdivided bypartition D, the flue A, passing backwardly over the oven, thencedownwardly under the oven and ashchainber into the outlet, and thedeflectors B, all arranged substantially as and for the purpose setforth.

In testimony whereof I hereunto affix my signature in presenccof twoWitnesses.
